trading nine RC BCTs (9*$302 million) for three cadre BCTs (3*$216 million) would save
about $2.0 billion per year.
A.3—NUMBER OF UNITS PER DEPLOYED BCT
The previous sections calculated the cost of a unit from each force. In order to
examine force structure tradeoffs for rotation, we also need to know the number of units
from each force that can support one unit deployed overseas. We call this the number of
units per deployed BCT. 129 This calculation requires that we make an assumption about the
rotation guidance and post-mobilization training time for each force. We define the number
of units per deployed BCT for force i as B i . This parameter is calculated by dividing the sum
of dwell time and mobilization length by the deployment length (mobilization length minus
post-mobilization training) as shown below.

Under the assumptions about rotation guidance made in the body of this paper (see
Table A.2), B 1 and B 3 are equal to three and B 2 is equal to nine as shown in Table A.5.

129 Klerman (2008) calls this the number of units in the force per unit boots-on-the-ground. These terms are
interchangeable [See Klerman (2008), Appendix A].
